Abstract:
In a paper published in the Journal of Applied Physics, three members of HP Labs' Quantum Science Research (QSR) group described their invention as a "crossbar latch," which provides the signal restoration and inversion required for general computing without the need for transistors.

The technology could result in computers that are thousands of times more powerful than those that exist today. "We are re-inventing the computer at the molecular scale," says Stan Williams, HP senior fellow and QSR director, and one of the authors of the paper.
